Katherine Heigl went casual in her baseball cap to do a little shopping in LA yesterday. This girl has been everywhere this summer, but tonight we finally get to see her back on the small screen (which is where most of you prefer to see her anyway). We've been all caught up with the new shows, but we're definitely excited to finally get back into Seattle Grace. We may not be huge fans of Gizzie, but the real life friendship between Katherine and T.R. is pretty cute — she even got him a puppy as a birthday gift! Callie would be so pissed.
